N. A. El-Nohy, M. N. El-Hammamy, M. El-Azab Farid, A. Attia & Moamen M. Elsayed · Journal of Pharmaceutical Research International · 2020

In this paper, we discuss the behavior of exotic nucleus 8B elastic scattering from heavy target 208pb at two different energies; 50 MeV (coulomb energy) and 170.3 MeV . For this purpose, we perform double folding (DF) calculations by treating 8B as a (7Be+P) and (7B+n) core-nucl...

Study of (p,n) Reaction in a Wide Energy Range

N. A. El-Nohy, M. N. El-Hammamy, S. Diab & A. M. El-Shinawy · Asian Journal of Research and Reviews in Physics · 2019

In this paper, the quasi-elastic scattering (p, n) reactions are studied for a wide range of target nuclei 13C, 14C, 48Ca, 90Zr and 208Pb and different incident energies (35-160 MeV). The phenomenological Optical model potential and density independent approaches are used for the...

Study of f(T) Dark Energy Model Using Different Choices of the Cosmological Scale Factor

Ayman A. Aly, A. Sabry & M. N. El-Hammamy · Journal of Pharmaceutical Research International · 2019

In this paper, we investigated the behaviors of some cosmological parameters as a function of redshift z using some dark energy models namely intermediate, logamediate and emergent scenarios of the universe adopting their cosmological scale factors in the frame work of the telepa...
